E rnesf Nunes United States Patent Ofiice 2,873,463 latented Feb. 17, 1959 PAINT BRUSH CONSTRUCTION Ernest Nunes, Sausalito, Calif. Application November 25, 1957, Serial No. 698,660 1 Claim. (Cl. 15-145) This invention relates to improvements in paint brush construction and has particular reference to a device for use in the cleaning of paint brushes.

The principal object of this invention is to provide means for this purpose which may be attached to an ordinary paint brush, whereby the same may be rotated about the medial axis of the paint brush bristles so that centrifugal action will cause the paint particles and solvents to be thrown away from the bristles in the cleaning operation.

A further object is to produce a device of this character which will not interfere with the customary handling of the paint brush and a device which may be used also to hang the brush on either the inside or the outside of a paint bucket when desired, as well as a device which will catch any drippings tending to run down the sides of the brush when painting overhead.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numbers are employed to designate like parts throughout the same.

Fig. 1 is a side elevation of a brush having my invention applied thereto;

Fig. 2 is an edge view of Fig. 1;

Fig. 3 is a top plan View of Fig. 1;

Fig. 4 is a top plan view of the brush body with the handle removed;

Fig. 5 is an enlarged fragmentary view showing a square pin;

Fig. 6 is a side elevation of Fig. 5;

Fig. 7 is a bottom plan view of my device;

Fig. 8 is a side elevation of Fig. 7, showing the same attached to the body of the brush;

Fig. 9 is a diagrammatic view showing the manner in which the brush body may be rotated to expel paint particles therefrom; and

Fig. 10 is a fragmentary detailed view showing the manner in which the brush may be suspended from the inside or outside of a paint can.

The ordinary paint brush consistsof a body portion to which the bristles are attached, and a handle portion for wielding the brush. It is a fact that it is very diflicult for the average person to clean the particles of paint which gradually work into the bristles at a point adjacent the body of the brush.

Applicant has therefore devised means for cleaning the brush by separating the handle from the body portion and inserting therebetween a flat platelike member having a pin which extends into the body of the brush and also into the handle thereof, which pin may be used in connection with a motor for the purpose of rotating the brush so that centrifugal action will cause the bristles to fly outwardly, thus releasing any paint particles from between the bristles and causing them to be dispelled through the centrifugal action. Almost every household now has such a motor, as for instance a power-driven drill or mixing device, which may be used for the purpose of rotating the brush.

In the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the handle of a paint brush, 6 the body and 7 the bristles thereof.

The construction thus far described is common to all paint brushes. My invention consists of separating the handle 5 from the body 6 through the medium of acut at the point 8 and inserting therebetween a plate 9 having a down-turned rim 11 which rim has extensions 12 and i 13, the purpose of which will be later seen.

A pin 14 extends into a bore formed in the handle 5 and a similar bore in the body 6. If desired, this pin may be split as shown in Figs. 7 and 8 so as to cause a tight friction between the parts. Pins 16 may also be employed to prevent rotation of the plate with respect to the body and handle of the brush.

In Figs. 5 and 6 I have shown the use of a squared pin designated as 14A, which may be used instead of a round pin, if desired.

In use, when the parts are assembled as shown in Fig. 1, the brush may be wielded in the customary manner and the projections 12 and 13 may be used to hang the brush on either the inside or the outside of the can as shown in Fig. 10. V

When it is desired to clean the brush, the handle 5 is pulled out from the body, which will expose the pins 14 and 16, and the pin 14 may then be engaged by the chuck 17 of a drill 18 or by any other motor-driven device whereby when the brush is placed in a bucket B and rotated any paint or solvent which is being used to clean the brush will be rapidly thrown from the brush bristles to the sides of the container, thus rapidly cleaning the brush to enable it to be used in further painting operations. This rapid cleaning of the brushes saves considerable time, and as painters now have a high wage scale, it is evident that my device will result in considerable saving to the user thereof.

It will thus be seen that my device will accomplish all of the objects above set forth. It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:

In combination with a paint brush having a bristlecarrying base and a separable handle, the bristles of said brush extending in the same direction as the elongated axis of said handle, a plate positioned between said base and said handle and having a pin extending through said plate and engaging said base and said handle, means carried by said plate to prevent rotation of said base and said handle with respect to each other, said plate having a downwardly turned edge, said edge being provided with extensions formed on the diametrically opposed sides thereof.
